[DataGridPro] Server-side tree data support

[MBilalShafi]

Part of #8179
Resolves #3377

Previews:
Server side tree data with server-side indexed pagination, sorting, filtering, and caching: https://deploy-preview-12317--material-ui-x.netlify.app/x/react-data-grid/server-side-data/tree-data/
Plain data server-side pagination, filtering, and sorting: https://deploy-preview-12317--material-ui-x.netlify.app/x/react-data-grid/server-side-data/#usage

Action items:

• A basic data source implementation via a dedicated hook
• New strategy processor for server-side tree data
• Allow use of the cache with the data source
• Make pagination.rowCount a controlled state (extracted to [DataGrid] Make rowCount part of the state #12381)
• Support x-data-generator to provide server-side filtered and sorted data (mock an actual data source) => (useDemoDataSource)
• Support server-side sorting, filtering, and (index-based) pagination.
• Make rows an optional prop (extracted to [DataGrid] Make rows an optional prop #12478)
• Extract cache into separate plugin + support imperative operations on it
• Support an internal cache
• Support unknown and estimated rowCount (extracted to [DataGrid] Support advanced server-side pagination use cases #12474)
• Support defaultGroupingExpansionDepth and isGroupExpandedByDefault
• Demos
  • Error handling (plain data)
  • Error handling (tree data)
  • Custom cache on plain data
  • Demos with swr and react-query
• Discoverability: Make the demos closer to the actual code to make it easy to copy-paste
• Perf: Optimize the rowTreeCreation and other processes of rows pre-processing
• Revisit naming conventions (e.g. DataSource vs DataManager vs DataProvider vs ?)
• Make loading a controlled prop ?
• Test coverage

Follow-up Items (for subsequent PRs):

• Publish API events to support advanced use-cases
• Tree data: Support filter/sort on Group column
• Cursor-based pagination demo
• Request cancellation support demo
• [DataGrid] Consider bringing back the error overlay #11399

Sidenote but these logger calls have the disadvantage that we need to create a new string in memory every time it runs, even if it doesn't log anything. If it's in a hot path, it could affect performance. A better option would be printf style calls that don't allocate new strings in the arguments, e.g. printf('new length: %i', props.rows.length).

While this simple cache is enough for demo purposes, we should provide a more advanced cache implementation required for real-world use cases – at least with configurable cache time.
What do you think?

I wanted to make the default cache as simple as possible, but I agree ttl could be added, as it's one of the most basic features of a cache. Added!
Let me know if it feels better now.
